Pillowflex Synthetic Down Pillow Insert 20x20 (Karate Chop) — Oversized Plush Hypoallergenic Poly-Cotton Shell

Pillowflex 20x20 Synthetic Down Pillow Insert (Karate Chop Pillow) is a plush, hypoallergenic sham insert designed to fill an 18x18 cover for a full, hotel-style look.

This handmade Pillowflex insert from Palmetto, GA pairs a resilient synthetic down fill with a soft poly-cotton shell to deliver a fluffy, durable cushion for decorative shams, accent pillows, and everyday lounger use. Engineered to be odorless, lint-free and free of flame retardants, it’s an all-purpose option when you want the look and feel of down without animal products or common allergens. The 20x20 size is intentionally larger than typical shams so you get a rounded, tailored finish when inserted into an 18x18 pillow cover.

How will this 20x20 insert change the look of my 18x18 shams?

Using a slightly oversized insert is the easiest way to achieve a plump, structured appearance. The Pillowflex Karate Chop Pillow fills corners and smooths the face of the sham so it reads as full rather than flat.

• Designed to be used with an 18x18 sham for a fuller silhouette
• Synthetic down fill keeps loft and resists flattening
• Poly-cotton shell provides a smooth, tailored surface
• Corner-to-corner measurement guidance ensures proper fit

Is this pillow insert allergy-friendly and easy to maintain?

The Pillowflex insert is made from hypoallergenic synthetic fibers and a poly-cotton cover, which reduces dust and lint compared with some natural fills. It’s a good choice for people who prefer cruelty-free options and want a low-odor, low-dust decorative insert.

Will this insert stay fluffy and support frequent use on sofas or beds?

Pillowflex builds these inserts to retain loft and recover well after being compressed, making them suitable for high-traffic areas like sofas and daily-made beds. The heavyweight, down-like texture resists quick flattening while remaining soft to the touch.

• Resilient synthetic fill holds shape through regular use
• Heavyweight feel for substantial, plush support
• Handmade construction in the USA for consistent quality
• Ideal for accent pillows, shams, and travel cushions

How should I choose the right size and keep the insert looking its best?

Measure your sham corner-to-corner while pulling the fabric taut along the outer edges; inserts should typically be larger than the cover for a filled look. For an 18x18 sham, the Pillowflex 20x20 insert is recommended to achieve a rounded, hotel-style finish.

• Measure shams before purchase; choose a slightly larger insert
• Fluff after unpacking and periodically to restore loft
• Spot clean and air dry; follow care label for deep cleaning
• Rotate and rearrange pillows to maintain even wear
